HENRY E. LEONARD, OF BROOKLYN, NEW YORK, ASSIGNOR TO C. B. COTTRELL 82; SONS COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

CUTTING AND FOLDING MACHINE.

Application filed April 27, 1917.

To all whom it may concern:

Be it known that I, HENRY E. LEONARD, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Cutting and Folding Machines, of which the following is a specification.

In cutting and folding machines when run at a high rate of speed, it has been found very difficult, if not impossible, to keep the traveling web from waving, which waving action prevents the positive feeding of the web to register.

My invention is directed to novel means which operate to prevent the traveling web from waving for insuring its positive feed to register.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Figure 1 is a detail face view of that part of the cutting and folding machine which includes my invention.

Fig. 2 is a section taken in the plane of the line IIII of Fig. 1, the web being omitted.

Fig. 3 is an enlarged detail section taken in the plane of the line IIIIII of Fig. 1, and

Fig. 4 is a similar view taken in the plane of the line IVIV of Fig. 1.

The web 1 is passed between the feed rolls 2, 3, through the rotary cutters 4L, 5, and from thence downwardly between the members 6, 7, of the web to the grippers 8 of the rotary carrier 9 of a sheet folding mechanism, for instance. The means which I have shown for preventing the traveling web from waving, for insuring its positive and accurate feed to the grippers 8 of the rotary carrier 9, comprises diverging guide rods which form the members of the guide member 7 which guide rods not only diverge as they lead toward the rotary carrier 9, but also are preferably gradually brou htinto close proximity to the guide member 6. These diverging guide rods, because of their engagement with the face of the web, will. cease the web as it passes Specification of Letters Patent.

downwardly, to be flattened out, thereby eliminating the waves in the web and insuring the accurate feed of the advance edge of the web to the grippers 8.

I have found that the means herein shown and described absolutely eliminates any waving action of the web, thus insuring the positive feed and accurate cutting of the web even when the web is traveling at a. very high speed.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to limit myself strictly to the structure herein shown and described, but- What I claim is:

1. In a machine of the character described, means engaging the leading end of the traveling web to prevent the traveling web from waving, whereby the leading end of the web is accurately and positively fed to a predetermined point, said means comprising web guide members between which the web is passed, one of the members having diverging guide rods gradually approaching the other member and arranged to act upon the web to flatten it out.

2. In a machine of the character described, a carrier, and means operating to prevent the traveling web from waving, for insuring the accurate and positive feeding of the leading end of the web to the carrier, said means comprising a web guide having guide rods diverging as they lead toward the carrier.

3. In a machine of the character described, a carrier, and means operating to prevent the traveling web from waving, for insuring the accurate and positive feeding of the leading end of the web to the carrier, said means comprising web guide members, one of the members having diverging guiderods gradually approaching the other guide member as they lead toward the carrier.

In testimony, that I claim the foregoing as my invention, I have signed my name this 20th day of A ril, 1917. p
